You could swap in the other Lift Pump (fuel pump) from the junk 617 or rebuild
your present pump.

Here is a link to the lift Pump repair kit.

I replaced these valves in the 240 pump and did make a difference for me.

Nice looking 123, I have a 78 parts car that color, I used a wax/cleaner on part of it and it really brings out the shine.

Make sure the rods are adjusted to the correct length on the linkages, so you get full fuel.

Make sure the in tank fuel screen is clean also
